Company email (February 2014):
"The only beers we serve that are not vegan are the Milk Stout (lactose) and the Oyster Stout. Otherwise you are good to go."

Company email (February 2009):
We never use Isinglass, Gelatin, very infrequently use honey, and will make everyone aware if we use other animal products (milk, egg white, etc) You should be pretty safe with everything on tap right now.

Company email (October 2008):
"Once I made an Oyster Stout and I have had great results with honey, but none of our current beers use any animal or animal products."
